HEATING APPARATUS.

Specification of`Letters Patent.

Patented March 1e, 190e.

Application filed January 19, 1909. Serial No. 473,126.

To all whom it may concern:

Be itfknown that I, JAMES L. WATERBURY, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification.

My invention relates to hot air heaters and is designed particularly for use in school rooms and other public places, although capable of application wherever it may be desired to maintain a uniform temperature and effect a thorough ventilaiionof the space at the same time.

A further object is to provide means, by means of wliich'the circulation of air around a heater may be controlled. y

In the accompanying drawings, forming part of this specification, Figure l is a perspective view of a heating' apparatus embodyin my invention, Fig. 2 is a pers ective view, il ustrating the construction of t e base of the heater casing, Fig, 3 is a detail, sectional view, illustrating the manner of supporting the slides in the base, by means of which the circulation of air within the casing is regulated.

The invention consists generally. in various constructions and combinations all `as heref inafter specified and in the claims.

In the drawing, Hue for the products of combustion leading to the foul air flue 4, and 5 is the fresh air intake extending through the wall of the building. These features are common to other inventions of mine and I make no claim to the same herein,

6 is a casing inclosing the heater and spaced therefrom and ornamented in any suitable way to present a neat, attractive appearance in the room.

7 is 'a ring an particularly pointed out ular in cross section, its Vertical fiange inc osing the lower end of the casing and its horizontal flange forming a seat or support for said casing. This ring may be east or made of angle bar iron and is supported by ornamental legs 8, arranged at intervals under the ring and resting upon the floor. Within the ring 7, I provide a series of straps 9, bent to form vertical loops and having guide-ways l() therein, in which the ends of curved panels l1 are adapted to slide. One leg of each loo is provided with a series of teeth 12 and eacli panel has a spring fin er 13 secured to each end and adapted to slide A over the surface of the tooth l2, the bevel of 2 represents a heater, 3 a

the tooth being the same on both sides to permit the finger to slide up and down thereon. The ends of the panels meet in the rear of the ornamental legs 8 and their lower edges contact with the floor and form close joints therewith, so that when the panels are lowered, entrance of air under the base and into the casing will b'e cut off; but u on raising any or all of the panels, a circu ation of air will be generated valong the floor and u between the heater and the casing wal Suitable handles 14 are provided on the pan-` els for convenience in moving them. I prefer to provide four panels under each base ring, but this number may be varied, if preferred and-each panel will be suitably ornamented to correspond with the ornamentation of the casin above.

I c aim as my invention 1. The combination, with a heater, of a casing inclosing the same and spaced therefrom, a ring having a seat to receive the lower end of said casing, and legs su Iporting said ring above the floor, and vertica y moving panels provided between said legs and adapted to slide upwardly within said ring and casing, for the purpose specified.

2. The combination, with a heater, of .a casing inclosing the same and spaced therefrom, a ring having a seat to receive the lower end of said casing, and legs su porting said ring, panels slidably mounted3 within said ring and having lower edges adapted to contact with the floor, said panels filllng the space below said ring and between said le s, and means for supporting said panels at different el evations. from the floor, substantially as described.

3. The combination, with a heater, of a casing inclosing same and spaced therefrom, a basehaving legs whereon said easing is seated, openings being provided beneath said base and. casing, and panels havin ornamental outer faces fitting within said base and vertically slidable and arranged to close said openings.

4. The combination, with a heater, of a casing inelos' same and spaced therefrom, a base providlgdwith legs whereon said casing is seated, panels arranged to close the space between said base and the floor, verticall arranged loops mounted on said base and iaving guidewa s wherein said anels are sIidabIe, said oops having rate et teeth formed thereon, and spring fingers mounted on said 'panels and arranged to engage the teeth of said ratehet and thereby hold said close the openings between the legs supportanels at any desirable elevation fromthe ing said base, the movement of said panels oor. allowing the admission of air beneath the 5. The combination, with a heater, of a said easing or the shutting o' of the same. easing inolosing the same and spaced there- In witness whereof, I have hereunto set my 15 from7 a base having a seat to receive the hand this 4th day of January 1909. lower end of said casing, and legs supporting JAMES L. WATERBURY. said base above the loor, and movable panels Witnesses: arranged between the seat for said casin in y RICHARD PAUL, 10 said base and the floor line and adapte to .J. A. BYINGTQN.
